CHARLES IV. ROEPPER, OF ALLIANCE, OHIO.

BRAKE-SHOE.

SPECIFICATION forming part of Letters Patent No. 426,068, dated April 22, 1890.

Application filed May 31, 1889. Serial No. 312,776. (No model.)

To all whom, it may concern:

Be it known that 1, CHARLES W. ROEPPER, a citizen of the United States, and a resident of Alliance, county of Stark, and State of Ohio, have invented certain new and useful Improvements in Brake-Shoes, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle so as to distinguish it from other inventions.

In this form of shoe I aim to reduce the amount of wearing-surface on the inner treadcontacting portion of the shoe and provide openings in said portion and inclines leading to said openings, whereby the wearings and grindings caused by the contact of said inner tread-contacting portion with the wheel may be easily and speedily conducted to the openings formed through the face of said tread contacting portion and thence discharged. In this form of shoe no opportunity is given for the said wearings or grindings to catch in the shoe or collect in said tread portion and become fused, as the inclines are continuous from the contact portion to the openings.

Referring to the drawings, Figure 1 is a transverse sectional view taken on the dotted line 10 w of Fig. 5. Fig. 2 is a transverse sectional view taken on the dotted line y 3 of Fig. 5. Fig. 3 is a transverse sectional view taken on the dotted line a: as of Fig. 6. Fig. 4 is a transverse sectional view taken on the dotted line a c of Fig. 6, all said views being taken in the directions indicated by the arrows. Fig. 5 is a face view of one form of brake-shoe. Fig. 6 is a face view of a second form of brake-shoe.

A is the outer tread-contacting portion of the shoe, and B the flange-contacting portion of the same. The inner contacting portion C is provided with a rib D, that extends 0bliquely from one side of said inner tread portion to the opposite side of the same. Openings 0 are formed intermediate of said rib and the sides of said inner tread. portion, and the two edges (1 of said rib incline downwardly from the contacting portion of said rib to the openings. The opposite inclined 5o edges of the inner tread-contact portions I also designate as d.

The rib may be made either of angular or curved formation, as shown in the two fig ures herein; but any such variance does not depart from the principle of invention as set forth in the claims.

The broad feature of providing openings in the inner tread portions of the shoe shown and described in this specification I do not broadly claim herein, as I claim this feature in another application simultaneously pending herewith, viz., application Serial No. 312,77 7.

I designate that portion of the shoe that 6 engages or has contact with the flange of the wheels as the flange-contact or flange-contacting portion, while that portion of the shoe thatis opposite to and covers, or m ay be adapted to have engagement with, the inner tread 7o portion of the wheel, whichis that portion of the wheel most likely to be worn down by engagement with the rail, I designate as the inner tread-contact or contacting portion of the shoe. The out-er tread-contact or contacting portion of the shoe is intended to signify that portion of the shoe lying outside of the inner tread-contact portion, said outer tread-contact portion being adapted to have engagement with the outer tread portion of the wheel.

The foregoing description and accompany ing drawings set forth in detail mechanism in embodiment of my invention. Change may be made therein, provided the principles of construction respectively recited in the following claims are retained and employed.

I therefore particularly point out and dis tinctly claim as my invention 1. In a brakeshoe, an inner tread-contact o portion provided with a rib extending obliquely and sinuously from one edge to the other of said contact portion, said rib extending the greater portion of the length of said brake-shoe and having acontinuous and un- 5 broken surface, substantially as set forth.

2. In a brake-shoe, an inner tread-contact portion provided with a rib extending ob liquely from one side of said inner tread por- In testimony thatIelaim the foregoing to be tion to the opposite side of the same, recesses my invention I have hereunto set my hand being formed intermediate of said rib and the this 25th day of May, A.
